### 2. Set Proxy on Firefox

* Open Firefox Settings (CMD+,)
* Search for Proxy and open the proxy settings
* Select Use system proxy settings, or enter the Proxy IP and Port manually

### 3. Install Proxyman CA to Firefox

1. Open `http://proxy.man/ssl` in Firefox and download the certificate to your Downloads folder

2\. Open Firefox Settings (CMD+,) and open the View Certificates window

3\. Open the Authorities tab and click the Import button
